If you change the heads, cam, intake, exhaust, etc. to raise the rpm on the 327 so that the piston speed matches that of the 305 then yes that is true.

BUT piston speed is almost never a limiting factor on a street engine and we're not discussing two completely different engines, but rather two identical engines with the exception of the piston diameter and crankshaft throw.

The 327 will have more power at every engine speed when compared to an equally built 305.
